Odds of Getting In
Most laypeople are not clamoring to become priests, and an even smaller population endeavor to become exorcists. Chances are, if you've got a hankering to rid the world of evil one host at a time, you’ll have a good shot.
An exorcist is a professional, like a teacher, a doctor, a comedian. He's got to know the area in which he wants to work. How many churches are there? What's the political climate? And if he believes what Father Gabriele Amorth and Father Jeremy Davies do, knowing how many yoga studies, gay bars, and bookstores selling Harry Potter books there are is key. (It stands to reason that the more places that are welcoming to the devil, the better your chances.)
